Help please explain thank you .

If you have 3.6 g and 2.0 g of CO2 how many grams of HCI can you expect to produce

2 answers

convert to moles
write the equation, which will tell you how many moles of HCl you will get for each mole of CO2
Then convert that quantity back to grams.
It isn't obvious to me how one gets HCl from CO2.
